◉ Which solution was used as the negative control for Benedict's test?
Answer: water
◉ How do you know if the Benedict's test for reducing sugar is a
qualitative or a quantitative test? Answer: it is a qualitative test because
you can observe the presence or absence of reducing sugars but only
measure the relative amounts of sugars present.
◉ When testing for the presence of sugar, what are the limitations of the
Benedict's test? Select FOUR answers. Answer: It could not be used
with intensely colored samples
You cannot tell which reducing sugar is present (i.e., glucose vs. fructose
vs. maltose)
It cannot be used on a solid sample unless the sugars are extracted first
It doesn't detect sucrose and other non-reducing sugars, only small
reducing sugars
, ◉ Test tube 1 is a control. Why are we using distilled water as a control?
Are we using distilled water as a positive or negative control? Answer:
Since distilled water does not have any starch present, we can see what a
negative result looks like. It is a negative control.
◉ Test tube 2 is a control. Why are we using starch as a control? Are we
using starch as a positive or negative control? Answer: Since starch
solution has lots of starch present, we can see what a positive result
looks like. It is the positive control.
◉ How do you know if Lugol's iodine test for starch is a qualitative or a
quantitative test? Answer: It is a qualitative test because you observed
the color to indicate presence or absence of starch.
◉ Differentiate between a red-brown result in Lugol's iodine test for
starches and a red-brown result in Benedict's test for simple reducing
sugars. Answer: A red-brown result in Lugol's iodine test is a negative
result for starches and a red-brown result in Benedict's test is a positive
result for simple reducing sugars.
◉ What is used as a positive control in the lipid test? Answer: mineral
oil
◉ What is used as a negative control in the lipid test? Answer: water
